Heating coils

ABSTRACT

A heat exchanger for providing radiant heat, the device comprising a circular reflector which is inwardly dished on one side so to form a concave reflective surface of parabolic character, three circular heater coils of each a different size being positioned concentrically in front of the parabolic reflector, all of the heater coils being connected to a steam source by means of a hand operated controll valve, and the diametrically opposite side of the heating coil being connected to a steam outlet valve.

1 Claim, 4 Drawing Figures MTENTED JUN 2 6 I973 SNEEIZUFZ HEATING COILSThis invention relates generally to heat exchangers. More specificallythe present invention relates to radiant heaters.

A principal object of the present invention is to provide an improvedradiant heater which employes steam as a heat source for a series ofheater coils positioned in front of a parabolic reflector that directsheat rays from the heater coils in a forward direction.

Another object of the present invention is to provide a heating coilsconstruction that is designed particularly for being recessedinto a wallof a house for heating the rooms thereof.

Still another object of the present invention is to provide a heatingcoils construction which relatively thin so that it maybe convenientlyfitted into a wall without taking up space within the room itself.

Yet a further object of the present invention is to provide a heatingcoils construction which thus replaces the bulky and space consumingsteam radiators presently employed in many buildings.

Other objects of the present invention are to provide a heating coilsconstruction which is simple in design, inexpensive to manufacture,rugged in construction, easy to useand'efficient in operation.

These and other objects will be readily evident upon a study of thefollowing specification and the accompanying drawing wherein:

FIG. 1 is a front elevation view of the present invention,

FIG. 2 is a vertical cross sectional view taken on the line 2-2 of FIG.1,-

FIG. 3 is a side cross sectional view taken on the line 3-3 of FIG. 1,and

FIG. 4 is an enlarged crosssectional view taken on the line 4--4 of FIG.1.

Referring now to the drawing in detail, the reference numeral representsa heating coils construction of the present invention wherein there is acircular reflector 11 which upon its front side is inwardly dished toform a concave surface so to form a parabolic character. The reflector11 is made perferably of an alloy material such as aluminum alloy andmaybe made approximately' one-half inch thick.

An upper and lower embossment or pad 12 and 13 respectively areintegrally formed upon the front side 15 of the reflector, the padsproviding support means for a plurality of heating coils 16 each one ofwhich is of a different diametrical size and which are positionedconcentrically upon the reflector. Each pad is provided with a pluralityof transverse extending grooves 17 within each one of which one of theheating coils 16 is fitted and then rigidly secured by means of clamps18 or 19, each of the clamps 18 and 19 being likewise provided withgenerally semi-circular grooves 20 for fitting over the heating coils.The clamps 18 and 19 are secured to the pads 12 and 13 by means ofsecurement screws 21.

The lower of the pads 13 contains a control valve 22 that is handoperated and which selectively controls the movement of live steam 23from a steam pipe 24 to the heater coils 16.

The control valve 22 includes a rotating stem or cylinder 25 that isrotatably controlled by means of an external handle 26. The cylinder 25has an elongated groove 27 along one edge thereof which communicateswith a series of transverse extending openings 28 in the cylinder 25,the openings 28 each being adaptable to be aligned with openings 29 inthe pad 13, the openings 29 each communicating with an opening 30through the wall of the heatercoils 16 so to communicate with theinterior thereof. The groove 27 of the cylinder 25 also communicateswith an inlet opening 31 that communicates with the steam pipe 24. Thussteam can be controlled for moving from a steam source into the heatingcoils.

The upper pad 12 additionally supports a steam outlet valve 32 fromwhich steam may escape and from which air is vented from the heatingcoils so to permit the steam to travel from a steam producing boiler andinto the heating coils.

Appropriate O-ring seal means maybe provided between the reflector andthe coils so to prevent the steam from escaping.

In operative use, it is now evident that when the device is mountedvertically within a wall, radiant heat is directed outwardly there fromand into a room. The heating coils maybe of one-half inch diameter, andthe entire unit maybe approximately 3 inches in width.

Thus there is provided an improved heating coils construction.

What I Now claim Is:

1. A radiant heater, comprising:

a circular reflector member, constructed of aluminum alloy, having aconcave, parabolic-shaped surface for reflecting'heat rays outwardly;

a plurality of circular heating coils, each having different diameters,and mounted in a concentric arrangement in front of said concave surfaceof said reflector member, said heating coils having steam circulatingtherethrough;

an upper and a lower support pad, disposed on said concave surface ofsaid reflector member, for supporting said plurality of heating coils;

a control valve, coupled to said lower pad, for controlling the flow ofsteam into said heating coils; and

a steam outlet valve, coupled to said upper pad, for

venting said heating coils to the atmosphere.
